TO ALL WHOM T MAY CONCERN:

Be it knownthat I, lVILLIAM WEAVER, of Phoenixville, Chester county, Pennsylvania, have invented a Machine for Ceiling Wire to form Springs, 85e.; and I do hereby declare the following to'bc a i'ull, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters cl` reference marked thereon,

My invention consists of mechanism, fully described hereafter, whereby wire may be quickly and easily coiled, to form springs and other articles.

Inorderto enable others skilled in the art to make and use my invention, Iwill now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this speeication, and in whichl Figure 1 is a sectional elevation of my improved machine for ceiling wire.

Figure 2, a side elevation.

Figure 3, a plan View.

Figure 4, a detached sectional view of part of the machine; and

i lFif'gure 5, a section on the line 1 2, iig. 4.

A is a'wooden frame, which consists of side-pieces a a and cross-pieces 25.6, the whole being supported on suitable legs c c. To the cross-piece b are secured a stationary standard, B, and an adjustable standard B, a portion, d, of the latter projecting through a slot, x, in the cross-piece b, to which it isconfined by a detachableliey, e. In the standard B turns a spindle, c, to the outer end or" which is secured a crank-handle, f, and -nto a groove, y, in the spindle projects the upper end of a sliding plate, g, which is so secured to the standard B as i to be readily adjusted vertically thereon. To the inner end of the spindle C is secured one section of a metal fern-ier, D, which former, in the present instance, consists of two conical sections, h L, and an intermediate cylindrical section, z', a rod or shaft, C', secured to the section L, projectingr through the standard B', and having on the outside of the standard a thumb-nut, c.- A screw projection on the section it is adapted to a corresponding recess in the intermediate section z', and at the opposite end of the latter is a square projection fitting into a corresponding orifice in the section h. In the surface of the former D is cutthe spiral groove shown in lig. 3, and in the section h are a number of openings, j, to any of which maybe t'terl a detachable pin or staple, nz. At the rear of the frame A turns a detachable shaft, E, and to this shaft is secured a reel, F, containing a coil of wire,t, from which springs and other articles of coiled Wire are to be formed. The wire t passes between the jaws n n of a tension-guide, Gr, the two jaws being hinged together at r, and the distance to which theyY can be separated being regulated by a set-screw, s. At the inner end of `the jaw n" is a projection, g, in which is a recess, u; and in the upper surface of the jaw, near one side of` thesame, is a recess, o, iig. 5.

The operator seats himself on the crossspiece b', passes the wire t through the tension-guide G, and into the groove o, as shown in figs. 2 and 4, and secures the end of the wire to the pin m. He then takes the tension-guide G in his left hand, and with his right turns the spindle C, by means of the handle f, so as to impart a rotary motion, in the direction of its arrow, to the former D. As the former revolves, the operator holds the tension-guide so that the 'projection g shall bear against the former. He `is thus able to hold it in its position, however great the tension may be, while the wire is drawn between the jaws n n through the groove o and into the spiral groove w in the former. After the wire has been passed once round the former, the tension-guide is so adjusteil'that the portion of the wire which is above the surface et' the former, in the coil already made, shall project into the groove or recess u so that, as the former revolves, the spira-l wirel already on the same shall actas a guiding screw to movethe holder towards the section t. The operator will not therefore be required to guide the holder, which will always be in the position required to introduce the wire properly into the spiral groove. It a spring of the entire length ofthe former is required, the operation is continued until the groove w is entirely lled. The wire is then'eut, the slide g depressed, and the spindle C is drawn back until the three sections t /zv and can be separated, when the idouble helical spring coiled on the former may be removed. When a shorter spring` is required, the pin m is placed in one of the openings nearer the contre A"not the former, and the wire is then secured to the pin and coiled as before.

Forineis of diifcrent sizes and shapes may be used to form springs or other articles of coiled wire, differing in shape from that shown. Intermediate pieces z' of greater or less length than that shown muy be used, or may be entirely dispensed with, the standard B being adjusted ns may be required vto permit the .introduction of the different formers.

The instrument is portubie, simple ond chen-p in construction, und muy be used with facility by workmen of ordinary skill.

I claim as my invention, ond desire to secure by Letters Patent- I. The frame A, with its standards B und B', und revolving former D; the Whole being constructed,

arranged, und operating substnntully as und for the purpose described.

2. rlhe tension-guide G, consisting of the jaws n n', with the projection q and recesses 0 and u, the whole being arranged for use in connection with the revolving former D, substantially us described. i

3. The grooved cylinder z', constructed and aduptxi for attachment to the-conicul grooved sections L h of the former D, substantially as and for the purpose specified. l

4. The former D, with its openings j, adopted for the reception of a detachable pin, in, for the purpose set forth.

In testimony whereof I have signed my nume to this specification in the presence of two subscribing witnesses.`
